AVFM 6.1 & Stingray
"AREA VELOCITY" FLOW METER, FIXED OR PORTABLE
AVFM 6.1
State-of-the-art instrument for the simultaneous measurement of fluid level and velocity for flow-rate calculation in open channels or pipes.
Features:
- Simple calibration
- Calibration parameters remain stored even in the absence of tension
STINGRAY
Portable instrument for the measurement of water level, velocity and temperature in open channels and partially-filled of pressurised pipes.
Features:
- Alkaline battery for extensive operating time
- Data stored to memory and presented as trend graphs and tables
- No calibration required
- Energy-saving display timeout
SUBMERGED SENSOR
- Measuring levels and velocity
